Abstract
Hydrophilic, high quantum yield, chemiluminescent acridinium compounds with increased light output, improved stability, fast light emission and decreased non specific binding are disclosed. The chemiluminescent acridinium esters possess hydrophilic, branched, electron-donating functional groups at the C2 and/or C7 positions of the acridinium nucleus.
